Former Apple Executives Recall Designing Touchscreen Interface of Original iPhone

As we near the ten-year anniversary of the iPhone later this week, a few stories posted online have delved into the rich history of where the device started, how the original team came up with the idea for the touchscreen smartphone, and what it was like reviewing the device back in 2007.

In a new video shared by The Wall Street Journal today, three former Apple executives -- Scott Forstall, Tony Fadell and Greg Christie -- have taken a look back at the first days of designing the iPhone with Steve Jobs. Apple's former senior vice president of the iPod division, Tony Fadell, recounted a time when Jobs showed him the company's first demo for what would become the iPhone's touch-based operating system.

"Steve goes, "Come over here I need to show you something." So he walked me into the room...and it was basically like a ping pong table sized demo with a projector that was projecting a Mac interface on it. And you could use your whole hand and you could touch different things on it, like it was a big big Mac.

It was literally a ping pong sized multi-touch display. And he goes, "I think this is gonna solve our problem."

Former Apple vice president of iOS, Scott Forstall, recalled a specific time in 2005 when the iPhone team was put on a deadline of two weeks to come up with a better design for the smartphone's user interface. Jobs was not satisfied at the time with early iterations of the iPhone's look, and told Forstall and the team that he'd give the project to another group at the company if they failed to deliver.

"The first time he saw it he was completely silent, he didn't say a thing. He didn't say anything, he didn't gesture, he didn't ask a question. Then he sat back and he said, "Show it to me again." And so we go through the whole thing again and Steve was pretty much blown away by the whole demonstration. It was great work.

Our reward for doing a great job on that demonstration was to, you know, kill ourselves over the next two and a half years."

In 2006, Forstall froze development across the iPhone's user interface divisions to force the team to focus on one troublesome part of the smartphone's UI: the keyboard. At the time, Forstall said it was difficult to use and that if someone tried to type out an e-mail, they'd just "give up."

Forstall explained that one of the best keyboards pitched by a developer had a few clever advantages over all the others designed by the team. Namely, it could intelligently predict words, so if a user would type "T," the keyboard would make the hit region for "H" larger -- while the actual key remained the same size -- so that common words such as "the" were easier to type.

The full ten-minute video created by The Wall Street Journal, which is called "How The iPhone Was Born: Inside Stories of Missteps and Triumphs," is well worth checking out. Other topics discussed by Forstall, Fadell, and Christie include the creation of the iPhone's visual vocabulary (like pinch to zoom and rubber banding to mark the end of a scrollable page), as well as the company's Fight Club secrecy tactics for "The Purple Project," the code name for the original iPhone's creation.
